Does anyone have any experience with add on lenses and adapters avaible for the Canon S60, i.e. 2X and Macro lenses? Just wondering if they are worth the investment. I have been pretty satisfied with the macro capability of the camera but wouldn't mind some additional clarity. I am however particularly interested in experience with any of the zoom lenses or 2x lenses I have seen for the 37 mm adapter kit. Thanks in advance for any information.
